I see some older posts on this topic wondering if there has been any new solutions. The post from 2019 suggests it works if you use a trigger campaign but that didn't work for me.
Essentially I'd like to "cc" a token (which contains an email address) when sending an Alert.
It works fine in a trigger context. Please explain your setup + observed behavior in more detail.
(It isn’t a “CC” though, it’s an alert destination like any other.)
